The The Efectiveness of Jamblang (Syzygium cumini) Leaves Extract Inclusion Skim Milk-Egg Yolk Extender on Motility and Viability of Aceh Cattle Spermatozoa during Pre-Freezing and Post-Thawing

The process of semen freezing causes an increase in free radicals concentration which can damage spermatozoa. The addition of natural ingredients in semen diluent is expected to solve this challenges. One of the natural ingredients that can be used is jamblang (Syzygium cumini) leaves. The objective of the current study was to investigate the quality of spermatozoa in Aceh cattle which was added with jamblang leaves extract in skim milk- egg yolk extender during pre-freezing and post-thawing. This study applied Completely Randomized Design (CRD) with 5 treatments and 5 replications. The treatments consisted of J0 = skim milk-egg yolk; J1 = skim milk-egg yolk + jamblang leaves extract 0.2%; J2 = skim milk-egg yolk + jamblang leaves extract 0.4%; J3 = skim milk-egg yolk + jamblang leaves extract 0.6%; and J4 = skim milk-egg yolk + jamblang leaves extract 0.8%. The parameters observed in this study were the percentage of motility and viability of frozen semen of Aceh cattle. The data obtained were analyzed using Analysis of Variance (ANOVA) and if differences were found, then it would be continued with Duncan's Multiple Distance test. The results showed that the addition of jamblang leaves extract in egg yolk skim milk significantly affected the percentage of motility during pre-freezing and post-thawing, significantly affected spermatozoa viability during pre-freezing and significantly affected the spermatozoa viability during post-thawing. J3 treatment (jamblang leaves extract 0.6 gram/100 ml) it should be higher than the other treatment, where the percentage of motility at pre-freezing and post-thawing were 55.48% and 52.71%, respectively, and the percentage of viability during pre-freezing and post-thawing were 56.59% and 53.94%, respectively. It was concluded that the addition of jamblang leaves extract in the skim milk-egg yolk extender affected the percentage of spermatozoa motility and viability of Aceh cattle during pre-freezing and post-thawing.
